Inventor Of Kevlar, Tougher-Than-Steel Fiber In Bulletproof Vests, Dies

 

 

 

 

 

 

” Police Lt. David Spicer took four .45-caliber slugs to the chest and arms at point-blank range and lived to tell about it. Like thousands of other police officers and soldiers shot in the line of duty, he owes his life to a woman in Delaware by the name of Stephanie Kwolek.

  Kwolek, who died Wednesday at 90, was a DuPont chemist who in 1965 invented Kevlar, the lightweight, stronger-than-steel fiber used in bulletproof vests and other body armor around the world.

  A pioneer as a woman in a mostly male field, Kwolek made the breakthrough while working on specialty fibers at a DuPont laboratory in Wilmington, Delaware. At the time, DuPont was looking for strong, lightweight fibers that could replace steel in automobile tires and improve fuel economy. “

 The New Frontline Fashion Statement

 

” The high demand for protection has spurred one vendor to produce cheap and lightweight bulletproof vests using X-ray film. The vests have become an essential safety measure for protest guards on Ratchadamnoen and around Government House. 

  Tests involving shots over a distance of five metres had shown an M-16 bullet penetrated 35 layers of X-ray film, a .357 bullet 28 layers, an 11mm bullet 18 layers, a .38 bullet 12 layers and a .22 bullet nine layers. The vendor uses 40 layers of X-ray film on the front and rear of each bulletproof vest. Each vest weighs less than 2kg. The vendor once made the vests from unbleached cloth, but he now orders them ready-made with the supporting steel plates removed. ”

Nanofoam Could Lead to New Body Armor

 

 

 

 

” The Army’s research and development arm has funded a three-year research program at University of California, San Diego investigating nanofoam for protection — the first foam armor endeavor ever, the college said.

“We’re developing nanofoams that help disperse the force of an impact over a wider area,” explained UC San Diego professor of structural engineering Yu Qiao. “They will appear to be less rigid but will actually be more resistant than ordinary foams.”

Qiao’s nanofoam may someday protect soldiers’ brains from blast trauma and prevent blast-induced lung injury. It may also be used to protect buildings from blasts.”

” Scientists have theorized that paper-thin composite nanomaterials could stop bullets just as effectively as heavy weight body armor, but progress has been hampered by their inability to reliably test such materials against projectile impacts. Researchers at MIT and Rice University have developed a breakthrough stress-test that fires microscopic glass beads at impact-absorbing material. Although the projectiles are much smaller than a bullet, the experimental results could be scaled up to predict how the material would stand up to larger impacts. “
